Another photo from Yellowstone National Park, the Norris Geyser Basin area.
While planning the walk around Norris Geyser Basin I hoped to see world largest geyser called Steamboat to erupt, however one must be really lucky to see its eruption. If you realize it is only erupting once a few years, I was not so dissapointed in the end :) The Norris Basin area is colourful and include lots of interesting features for photography.

Norris Geyser Basin is the hottest geyser basin in the Yellowstone park.
The Basin consists of three main areas: Porcelain Basin, Back Basin, and One Hundred Springs Plain.
Unlike most of other geyser basins in the park the waters from Norris are acidic rather than alkaline. The difference in pH allows for a different class of bacterial thermophiles to live at Norris, creating different color patterns in and around the Norris Basin waters.
The tallest active geyser in the world is Steamboat Geyser and it is located in Norris Basin. Steamboat has an erratic and lengthy timetable between major eruptions. During major eruptions, which may be separated by intervals of more than a year (the longest recorded span between major eruptions was 50 years), Steamboat erupts over 300 feet (90 m) into the air. Steamboat does not lie dormant between eruptions, instead displaying minor eruptions of approximately 40 feet (12 m).
Norris Geyser Basin periodically undergoes a large-scale, basin-wide thermal disturbance lasting a few weeks. Water levels fluctuate, and temperatures, pH, colors, and eruptive patterns change throughout the basin. During a disturbance in 1985, Porkchop Geyser continually jetted steam and water; in 1989, the same geyser apparently clogged with silica and blew up, throwing rocks more than 200 feet (61 m). In 2003 a park ranger observed it bubbling heavily, the first such activity seen since 1991. Activity increased dramatically in mid-2003.
